six different DCT (Discrete Cosine Transform based image fusion techniques are presented Image fusion using DCT based demo programme is presented.
computes the sequency-ordered discrete Hadamard transform
computes the discrete walsh transform
function [g] = FFTPF1D (X,binsize, f, P) Discrete Fourier Transform Low/High Pass Filter. % This is a simply implement of such a filter for a given 1-D data. X: the array of you data, each data point is a bin of signal ...
computes the naturally-ordered discrete Hadamard transform
This article consists of a brief discussion of the energy density over time or frequency that is obtained with the wavelet transform. Also an efficient algorithm is suggested to calculate the continuous transform with the Morlet wavelet. The...
A Coding Convention for C Code is a multi-platform compatible script that makes it easier for us to read each other's code, here are a few guidelines to follow when writing C code.
Image compression using wavelet transform
*wavelet transform give better information about non-stationary signals in time domain
Wavelet transform for image coding Wavelet transform related functions specifically designed to be used as a tool for image/video compression. The core of the toolbox consists of one-dimensional (1D) wavelet analysis and synthesis functions....
The Berkeley Wavelet Transform (BWT) comprises four pairs of mother wavelets at four orientations. Within each pair, one wavelet has odd symmetry, and the other has even symmetry. By translation and scaling of the whole set (plus a single constant...
Generate Pascal and/or C code starting from a simple HTML-like file. You insert then the output in your program and with a simple call to a function you'll see on the screen the linked HTML! In the future the format will be HTML/XML.
C Code Completer enhance writing C code with auto popupping words, it also shows parameter list, the header file they are defined in, and what they do. This can be also used to compile if Borland Turbo C is present in the same directory.Based on .NET
A tool to transform single channel C code into multichannel C code. We are using pyparsing to provide a C sensitive find/replace mechanism. The resulting code is more testable than hand edited. The initial source base is DSP code.
This demo works on only the Approximate region of the Wavelet Transform
JPEG compression using Discrete Cosine Transform Technique In this code, Run Length Encoding is used to compress the Normalized DCT Coefficients, and corresponding Decoding techniques are used to decompress the image.
The library includes compiled FIR filters, redundant and non redundant wavelet transform with dynamically sized channels, with applications to denoising and differentiation.
Image can be compressed using KL transform the code demonstrates the method
Y = DCTN(X) returns the discrete cosine transform (DCT) of X.
X = IDCTN(Y) returns the inverse discrete cosine transform (IDCT) of Y.
Y = DSTN(X) returns the discrete sine transform (DST) of X.
X = IDSTN(Y) returns...
Metamunger is a plug-in based code generation framework that lets you generate, manipulate and transform source code and documentation. Supports Java, C#, C++, XML Schema, and several other formats.
